SEED charter schools follow the “no excuses” model of education, but what makes them really different is that students board at school five days and return to their parents only on weekends. SEED schools try to imbue their captive students with middle class attitudes and skills on top of purely academic lessons. Vilsa Curto and Roland Fryer have compared students who got into a SEED school by winning a lottery with those who were turned away. (All the students are black and poor.) SEED students did better, a lot better.
How much better? To quote the authors
Our lottery estimates reveal that SEED is effective at increasing achievement among poor minority students. Students who enroll in SEED increase their achievement by 0.211σ in reading and 0.229σ in math, per year. Thus, SEED schools have the power to eliminate the racial achievement gap in four years.
It’s just a first study but still, take another look at that last sentence.
